Disclosure of Invention

The utility model aims to provide a light shielding sheet with a protective structure, so as to solve the problem that the conventional light shielding sheet is not provided with the protective structure in the prior art, and the surface of the light shielding sheet is easily scratched or damaged, so that the light shielding sheet cannot be used.

In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides a shading sheet with protective structure, includes the shading sheet body, the outside of shading sheet body can be dismantled and be connected with protective housing, protective housing's bottom fixedly connected with spacing post, the outside of shading sheet body is provided with the spacing groove, spacing post joint is inside the spacing groove, upper and lower both ends of shading sheet body paste respectively have protection film and lower protection film.

Preferably, four groups of fixing feet are fixedly connected to the outer side of the protective shell, and fixing holes are formed in the upper end faces of the fixing feet.

Preferably, the limit post is matched with the limit groove.

Preferably, an upper cover is detachably connected to the upper end of the protective shell.

Preferably, the upper cover and the protective shell are made of transparent materials.

Preferably, the number of the limit posts and the limit grooves is four.

Compared with the prior art, the utility model has the beneficial effects that: the shielding film with the protective structure is provided with the protective shell, the upper cover, the upper protective film and the lower protective film to be mutually matched for use, so that the shielding film can be protected, the damage of the shielding film is avoided, and the service life of the shielding film is prolonged well;

this anti-dazzling screen with protective structure is through being provided with spacing post and spacing groove for when installing in protective housing to anti-dazzling screen, avoid anti-dazzling screen to rotate at will, improved anti-dazzling screen's installation steadiness.
